Application iled May l5, 1919. Serial No. 297,442.

To all whom t may concer/n.'

Be it known that l, WILLIAM J. THE- BAULT, a citizen of Canada, residing at Sydney Mines, in the Province of Nova Scotia, Dominion of Canada, have invented certain new and useful improvements in Combined Rail Chairs and Antispreading Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to combined rail chairs and antispreading devices.

rllhe object of the invention resides in the provision of a combined rail chair and antispreading devices which will solidly support the rails and eiiciently prevent spreading thereof.

A further object of the invention resides in the provision of a device of the character named which will be simple in construction, easily applied and comparatively cheap to manufacture.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

1n describing the invention in detail reference will be had to the accompanying drawings, wherein like characters of reference denote corresponding parts in the several views, and in which- Figure 1 is a plan view showing the invention applied to a railway tle and securing the rails together;

Fib. 2, a section on the line 2-2 of Fig. 1;

Fig. 3, a section on the line 3-3 Fig. 1;

Fig. 4l, a perspective view of the adjustable rail clamping element employed in each corresponding section of the device, and

Fig. 5, a perspective view of the base plate and the rail clamping element formed integral therewith. l

Referring to the drawings 10 indicates a railway tie and 11 the rails supported thereby.

The improved chair and antispreading device comprises corresponding opposed sections B. Each section comprises a base plate 12 provided with an opening 13. Formed integral with the base plate 12 is a rail clamping element 14 adapted to be disposed against the outer side of the rail. Each section B further embodies an adjustable rail clamping element 15 which projects through the opening 13 and can be adjusted to a limited extent toward and away from the element 14:. rlhis element 15 is adapted to engage the inner side of a rail. The base of the element is beveled as at 16 and the walls of the opening 13 are correspondingly beveled as at 17. The element 15 is provided with spike openings 18 whereby said element may be secured to the tie when in proper position. The plate 12 is likewise provided with spike openings 19 for securing the plate to a tie. Suitably secured to the inner end of each plate 12 is a threaded member 20, the threads of one member 2O being opposite to the threads of the other member, and said members are connected by an interiorly threaded sleeve 21 having openings 22 therein for the reception of an operating lever to effect rotation of the sleeve. Owing to the fact that the threads on the member 20 are opposite it will be apparent that the rotation of the sleeve 21 in one direction will draw the plates 12 toward each other.

In applying the device the elements 15 are rst secured to the tie in proper position and then the respective plates are engaged over said elements. The rails are then disposed against the elements 15 and the sleeve 21 operated to Vdraw the elements 111 against the outer sides of the rails. When the plate is properly positioned suitable spikes are engaged through the openings 19 into the tie.

lWhat is claimed:-

A combined rail chair and an antispreading device comprising tie engaging end plates, means for adjusting said plates toward each other, each of said plates 'having an undercut opening extending longitudinally thereof, a rail clamping element rigidly carried by the plate outwardly of the opening, a second rail clamping element separate from the plate and extending through the opening therein, and having an enlarged lower end portion extending into the undercut portion of the opening to hold the clamping element against upward movement, means for securing the second clamping element to a tie, and means for securing the plate to a tie.

In testimony whereof, I affix my signature in the presence of two witnesses.

WILLIAM J. THEBAULT.
